[0155] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0156] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0157] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0158] The embodiments of the present application provide an information processing method and apparatus to reduce the complexity of network device scheduling.

[0159] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0160] See also Figure 1 , Figure 1 is a flowchart of an information processing method provided in an embodiment of the present application, which is applied to a terminal, such as Figure 1 As shown, the following steps are included:

[0161] Step 101: Determine a first symbol set.

[0162] Among them, the first symbol set is used for switching between SBFD symbols and traditional symbols, reserving switching time for terminals and / or network devices, that is, the first symbol set is used for switching SBFD symbols to traditional symbols, or, the first symbol set is used for switching traditional symbols to SBFD symbols, and the traditional symbols include one or more of uplink symbols U, downlink symbols D and flexible symbols F.

[0163] In the embodiment of the present application, the terminal may determine the first symbol set in multiple ways.

[0164] Method 1: Determine the first symbol set according to protocol regulations.

[0165] The agreement stipulates that:

[0166] The K symbols before a group of continuous SBFD symbols are used as the first symbol set; or, the K symbols after a group of continuous SBFD symbols are used as the first symbol set; wherein K is an integer greater than or equal to 0. The K value may be a predefined value, for example, the K value may be defined according to factors such as SCS (Subcarrier Spacing), FR1 (Frequency range 1), FR2 (Frequency range 2), and / or a switching position.

[0167] For example, the first symbol set may be the K symbols before a group of consecutive SBFD symbols, for example, symbol nK, n-K+1,…, n-1, where n is the position of the first SBFD symbol in a group of consecutive SBFD symbols; or, the first symbol set may be: the K symbols after a group of consecutive SBFD symbols are the first symbol set, for example, symbol n+1, n+2,…, n+K, where n is the position of the last SBFD symbol in a group of SBFD symbols.

[0168] In this embodiment of the present application, the K symbols of the first symbol set include:

[0169] A symbol configured as a downlink symbol D and / or an uplink symbol U. For example, a symbol configured as a downlink symbol D and / or an uplink symbol U by a cell-level common configuration tdd-UL-DL-ConfigurationCommon; and / or a symbol configured as a downlink symbol D and / or an uplink symbol U by a terminal-level configuration tdd-UL-DL-ConfigurationDedicated.

[0170] In a second method, the terminal determines the first symbol set according to the instruction of the network device (such as a base station) and the protocol specification. This method may also include any of the following methods:

[0171] 2.1, in this way, the terminal receives the first information sent by the network device, the first information is used to indicate the number of symbols K of the first symbol set, and obtain the position of the first symbol set specified by the protocol, the position of the first symbol set includes before a group of continuous SBFD symbols or after a group of continuous SBFD symbols. Afterwards, the terminal determines that the K symbols before a group of continuous SBFD symbols are the first symbol set, or determines that the K symbols after a group of continuous SBFD symbols are the first symbol set according to the number of symbols K and the position of the first symbol set; wherein K is an integer greater than or equal to 0.

[0172] The network device may send the first information via RRC (Radio Resource Control) signaling.

[0173] 2.2, in this manner, the terminal receives the third information sent by the network device, and obtains the position of the first symbol set specified by the protocol, the position of the first symbol set includes before a group of continuous SBFD symbols or after a group of continuous SBFD symbols, the third information is used to determine the first parameter, and the first parameter is used to determine the number of symbols K of the first symbol set. Afterwards, the terminal can use the K symbols before a group of continuous SBFD symbols as the first symbol set, or use the K symbols after a group of continuous SBFD symbols as the first symbol set according to the number of symbols K and the position of the first symbol set; wherein K is an integer greater than or equal to 0.

[0174] For example, the third information may include information about the first parameter, and the terminal determines the first parameter according to the third information. Assuming that the first parameter is α, for example, the number of symbols K in the first symbol set is Where T is the symbol length, In another example, the number of symbols K in the first symbol set is Where T is the symbol length, N TA,offset Determined by n-TimingAdvanceOffset or according to the protocol, Indicates rounding up.

[0175] The method for obtaining K is the same as that in method 1, and the contents of the K symbols of the first symbol set are the same as those in method 1. The network device may send the third information through RRC signaling.

[0176] Method three: The terminal determines the first symbol set according to an instruction of a network device (such as a base station).

[0177] In this manner, the terminal may receive second information sent by the network device, and determine the first symbol set according to the second information, wherein the second information is used to indicate the position of each symbol included in the first symbol set. The network device may send the second information via RRC signaling.

[0178] Optionally, the second information may also indicate information of the SBFD symbol, so that the terminal may accurately determine the first symbol set. The contents of the K symbols of the first symbol set are the same as those in the first mode.

[0179] Optionally, in an embodiment of the present application, the terminal may further receive fourth information sent by the network device, wherein the fourth information is used to indicate information of the SBFD symbol, and then the terminal may determine the group of continuous SBFD symbols according to the fourth information, thereby facilitating the terminal to determine the positions of the K symbols. The network device may send the fourth information by RRC signaling or the like.

[0180] Step 102: Determine the validity of a sending opportunity and / or a receiving opportunity according to the first symbol set.

[0181] Here, determining the validity of the sending timing and / or receiving timing can also be understood as determining whether the sending timing and / or receiving timing is valid, for example, whether data can be sent at the sending timing and received at the receiving timing.

[0182] In the embodiment of the present application, the terminal may determine the validity in one or more of the following ways:

[0183] If at least one symbol corresponding to the sending opportunity and / or receiving opportunity overlaps with at least one symbol of the first symbol set, discarding or delaying the sending opportunity and / or receiving opportunity;

[0184] If at least one symbol corresponding to the sending timing and / or receiving timing overlaps with at least one symbol of the first symbol set, rate matching is performed on the part of the sending timing and / or receiving timing that does not overlap with the first symbol set;

[0185] If the transmission opportunity partially or completely overlaps with the H symbols after the first symbol set (that is, the first H symbols of a group of continuous SBFD symbols), discard or delay the transmission opportunity;

[0186] If at least one symbol corresponding to the transmission opportunity overlaps with H symbols after the first symbol set (that is, the first H symbols of a group of continuous SBFD symbols), rate matching is performed on a target symbol, where the target symbol is a symbol that does not overlap with the transmission opportunity and the first symbol set and the H symbols;

[0187] The receiving timing on the M symbols after the first symbol set (that is, the first M symbols of a group of continuous SBFD symbols) is valid;

[0188] Among them, H and M are specified by the protocol or notified by the network device to the terminal, and H and M are integers greater than or equal to 0.

[0189] Optionally, the terminal may also determine that the N symbols after the group of continuous SBFD symbols have a valid sending opportunity, wherein N is specified by the protocol or notified to the terminal by the network device, and N is an integer greater than or equal to 0. The terminal may send an uplink on the N symbols, and the uplink may be dynamically configured and / or configured by a high layer.

[0190] In the embodiment of the present application, H, K, M, N, etc. can take values ​​of 0, 1, 2, 3 or 4, etc.

[0191] In an embodiment of the present application, since the terminal can determine the validity of the sending timing and / or receiving timing based on the determined first symbol set, even if the network device configures or schedules uplink transmission or downlink reception for the terminal on the determined first symbol set, the terminal may not send uplink or receive downlink, thereby solving the problem of switching between symbols and reducing the complexity of network device scheduling.

[0192] See also Figure 2 , Figure 2 is a flowchart of an information processing method provided in an embodiment of the present application, which is applied to a network device, such as Figure 2 As shown, the following steps are included:

[0193] Step 201: determine a first symbol set, and / or send indication information to a terminal, wherein the indication information is used to determine the first symbol set.

[0194] The first symbol set is used for switching between SBFD symbols and traditional symbols, and the traditional symbols include one or more of uplink symbols U, downlink symbols D and flexible symbols F.

[0195] Specifically, the network device may determine the first symbol set according to a protocol provision, wherein the protocol provision includes:

[0196] The K symbols before a group of continuous SBFD symbols are taken as the first symbol set; or, the K symbols after a group of continuous SBFD symbols are taken as the first symbol set; wherein K is an integer greater than or equal to 0. The K value may be a predefined value, or the K value may be defined according to factors such as SCS, FR1, FR2 and / or switching position.

[0197] Specifically, the indication information may include first information, second information, third information, etc.

[0198] For example, the network device may send first information to the terminal, where the first information is used to indicate the number K of symbols in the first symbol set.

[0199] Alternatively, the network device may send second information to the terminal, where the second information is used to indicate the position of each symbol included in the first symbol set. Optionally, the second information is also used to indicate information of SBFD symbols.

[0200] Alternatively, the network device may send third information to the terminal, where the third information is used to determine a first parameter, where the first parameter is used to determine the number K of symbols in the first symbol set; wherein K is an integer greater than or equal to 0.

[0201] Optionally, the network device may further send fourth information to the terminal, where the fourth information is used to indicate information of the SBFD symbol.

[0202] The contents of the K symbols of the first symbol set may refer to the description of the aforementioned embodiment.

[0203] Step 202: Determine the validity of a sending opportunity and / or a receiving opportunity according to the first symbol set.

[0204] In the embodiment of the present application, the network device may determine the validity in one or more of the following ways:

[0205] If at least one symbol corresponding to the sending opportunity and / or receiving opportunity overlaps with at least one symbol of the first symbol set, discarding or delaying the sending opportunity and / or receiving opportunity;

[0206] If at least one symbol corresponding to the sending timing and / or receiving timing overlaps with at least one symbol of the first symbol set, rate matching is performed on a portion of the sending timing and / or receiving timing that does not overlap with the first symbol set;

[0207] If the receiving opportunity partially or completely overlaps with the H symbols after the first symbol set (that is, the first H symbols of a group of continuous SBFD symbols), discarding or delaying the receiving opportunity;

[0208] If at least one symbol corresponding to the receiving opportunity overlaps with H symbols after the first symbol set (that is, the first H symbols of a group of continuous SBFD symbols), rate matching is performed on a target symbol, where the target symbol is a symbol that does not overlap with the sending opportunity and the first symbol set and the H symbols;

[0209] The transmission opportunity on the M symbols after the first symbol set (that is, the first M symbols of a group of continuous SBFD symbols) is valid;

[0210] Optionally, the network device may also determine that the reception timing is valid for N symbols after the group of continuous SBFD symbols, wherein N is specified by the protocol or notified by the network device to the terminal, and N is an integer greater than or equal to 0. The network device may receive an uplink transmission sent by the terminal on the N symbols, and the uplink transmission may be dynamically configured by the network device and / or configured by the network device to the terminal through a higher layer.

[0211] Among them, H and M are specified by the protocol or notified to the terminal by the network device, and H and M are integers greater than or equal to 0. H, K, M, N, etc. can take values ​​of 0, 1, 2, 3 or 4, etc.

[0212] In an embodiment of the present application, since the terminal can determine the validity of the sending timing and / or receiving timing based on the determined first symbol set, even if the network device configures or schedules uplink transmission or downlink reception for the terminal on the determined first symbol set, the terminal may not send uplink or receive downlink, thereby solving the problem of switching between symbols and reducing the complexity of network device scheduling.

[0213] The specific implementation process of the embodiments of the present application is described below in combination with different embodiments. Among them, the network device is described by taking a terminal as an example.

[0214] In one embodiment of the present application, the terminal switches from the uplink symbol U to the SBFD symbol.

[0215] In this embodiment, the protocol may stipulate that the K symbols before a group of consecutive SBFD symbols are used as the first symbol set, such as symbols nK, n-K+1, ..., n-1, where n is the position of the first SBFD symbol in the group of consecutive SBFD symbols. Figure 3 The K symbols corresponding to T_switch are the first symbol set. The terminal and the base station determine the first symbol set according to the protocol.

[0216] Alternatively, the base station indicates through RRC signaling that the number of symbols in the first symbol set is K, and the protocol stipulates that the K symbols before a group of consecutive SBFD symbols are the first symbol set, for example Figure 3 The K symbols corresponding to T_switch in the first symbol set are the first symbol set. The terminal determines the first symbol set according to the K value and the positions of the K symbols specified by the protocol.

[0217] Alternatively, the base station indicates the third information through RRC signaling, and the third information is used to determine the parameter α, and the parameter α is used to determine the number of symbols K of the first symbol set. The protocol stipulates that the K symbols before a group of consecutive SBFD symbols are the first symbol set. The terminal determines the first symbol set according to the parameter α and the protocol. For example, the number of symbols K of the first symbol set is Where T is the symbol length. For another example, the number of symbols K in the first symbol set is Where T is the symbol length, N TA,offset Determined by n-TimingAdvanceOffset or according to the table in the protocol.

[0218] Alternatively, the base station indicates the position of each symbol included in the first symbol set through RRC signaling. For example, the base station may further configure the first symbol set in the symbol configured as D, U or F through tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. For example:

[0219] tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated configure slotn+5 to D, and the base station uses RRC signaling to Figure 3 The symbols in slotn+5 are further indicated as {TTXXXXXXXXXXXX}, where {TT} represents the first symbol set and X represents the SBFD symbol. The terminal determines the first symbol set according to the RRC signaling instruction of the base station. Figure 3 In the example, the conversion time configured by the base station does not include the TA-offset time.

[0220] If the sending / receiving opportunity partially or completely overlaps with the first symbol set, the terminal discards the sending / receiving opportunity, delays the sending / receiving opportunity, or the terminal performs rate matching on the part where the sending / receiving opportunity does not overlap with the first symbol set.

[0221] Considering that the transmission on the uplink subband has a timing advance, in order to avoid the compression of the base station switching time caused by the transmission on the uplink subband arriving at the base station in advance, the first H symbols of the SBFD symbol may not be used for uplink transmission, for example Figure 3 H symbols corresponding to TA-offset in the frame format diagram. Alternatively, when the first symbol set configured by the base station is long enough, even if the transmission on the uplink subband has a timing advance, the base station still has sufficient switching time. At this time, the last M symbols in the first symbol set (i.e., the M symbols before a group of continuous SBFD symbols) can be considered for downlink transmission, for example Figure 4 The M symbols indicated by 41 in FIG. 4 can improve resource utilization. Figure 4 In the example, the conversion time configured by the base station includes the TA-offset time.

[0222] Optionally, considering that the transmission on the uplink subband has a timing advance, it can be considered that the terminal can send the uplink N symbols after a group of consecutive SBFD symbols, for example Figure 3 and Figure 4 In the frame format diagram, because there is a timing advance ( Figure 3 As indicated in 32, Figure 4 This part of the transmission will be aligned with the downlink timing when it arrives at the base station side, and may not compress the switching time from SBFD to U. Allowing N symbols after a group of consecutive SBFD symbols to transmit uplink can effectively utilize resources.

[0223] Optionally, on the terminal side, the terminal can determine whether it can switch between the two terminals according to its own switching time requirements and / or the switching time requirements of the base station. Figure 3 The resources indicated by 31 and Figure 4 The uplink is transmitted on the resource indicated by 42, and the switching time requirement of the base station may be specified by the protocol or notified by the base station.

[0224] In one embodiment of the present application, the terminal switches from the downlink symbol D to the SBFD symbol.

[0225] The K symbols before a group of consecutive SBFD symbols may be defined by a protocol as the first symbol set, for example, nK, n-K+1, ..., n-1, where n is the position of the first SBFD symbol in a group of consecutive SBFD symbols. For example, the protocol defines Figure 5 The K symbols corresponding to T_Switch in the first symbol set are determined by the terminal and the base station according to the protocol.

[0226] Alternatively, the base station indicates through RRC that the number of symbols in the first symbol set is K, and the protocol stipulates that the K symbols before a group of consecutive SBFD symbols are the first symbol set, for example Figure 5 The K symbols corresponding to T_switch in the first symbol set are the first symbol set. The terminal determines the first symbol set according to the K value and the positions of the K symbols specified by the protocol.

[0227] Alternatively, the base station indicates the third information through RRC signaling, and the third information is used to determine the parameter α, and the parameter α is used to determine the number of symbols K of the first symbol set. The protocol stipulates that the K symbols before a group of consecutive SBFD symbols are the first symbol set. The terminal determines the first symbol set according to the parameter α and the protocol. For example, the number of symbols K of the first symbol set is Where T is the symbol length. For another example, the number of symbols K in the first symbol set is Where T is the symbol length, N TA,offset Determined by n-TimingAdvanceOffset or according to the table in the protocol.

[0228] Alternatively, the base station indicates the position of each symbol included in the first symbol set through RRC signaling. For example, the base station may further configure the first symbol set in the symbol configured as D, U or F through tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. For example:

[0229] tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated configure slotn+5 to D, and the base station uses RRC signaling to Figure 5 The symbols in slotn+5 are further indicated as {TTXXXXXXXXXXXX}, where {TT} represents the first symbol set and X represents the SBFD symbol. The terminal determines the first symbol set according to the RRC signaling instruction of the base station. Figure 5 In the example, the conversion time configured by the base station does not include the TA-offset time.

[0230] If the sending / receiving opportunity partially or completely overlaps with the first symbol set, the terminal discards the sending / receiving opportunity, delays the sending / receiving opportunity, or the terminal performs rate matching on the part where the sending / receiving opportunity does not overlap with the first symbol set.

[0231] Considering that the transmission on the uplink subband has a timing advance, in order to avoid the compression of the base station switching time caused by the transmission on the uplink subband arriving at the base station in advance, the first H symbols of the SBFD symbol may not be used for uplink transmission, for example Figure 5 H symbols corresponding to TA-offset in the frame format diagram. Alternatively, when the first symbol set configured by the base station is long enough, even if the transmission on the uplink subband has a timing advance, the base station still has sufficient switching time. At this time, it can be considered to use the last M symbols in the first symbol set (or the M symbols before a group of continuous SBFD symbols) to receive the downlink transmission, for example Figure 6 The M symbols corresponding to 61 in , thereby improving resource utilization. Figure 6 In the example, the conversion time configured by the base station does not include the TA-offset time.

[0232] Optionally, considering that the transmission on the uplink subband has a timing advance, it can be considered that the terminal can send the uplink N symbols after a group of consecutive SBFD symbols, for example Figure 5 and Figure 6 In the frame format diagram ( Figure 5 As indicated in 51, Figure 6 Because of the timing advance, this part of the transmission will be aligned with the downlink timing when it arrives at the base station side, and may not compress the switching time from SBFD to U. Allowing uplink transmission in N symbols after a group of consecutive SBFD symbols can effectively utilize resources.

[0233] Optionally, on the terminal side, the terminal can determine whether it can switch between the two terminals according to its own switching time requirements and / or the switching time requirements of the base station. Figure 5 (resource indicated by 52) and Figure 6 The uplink is transmitted on the resource (indicated by 63), and the switching time requirement of the base station may be specified by the protocol or notified by the base station.

[0234] In one embodiment of the present application, the terminal switches from the SBFD symbol to the D symbol.

[0235] In this embodiment, the K symbols after a group of consecutive SBFD symbols may be defined as the first symbol set by a protocol, for example, symbols n+1, n+2, ..., n+K, where n is the position of the last SBFD symbol in the group of SBFD symbols. Figure 5 The K symbols corresponding to T_Switch_1 are the first symbol set. The terminal and the base station determine the first symbol set according to the protocol.

[0236] Alternatively, the base station indicates through RRC that the number of symbols in the first symbol set is K, and the protocol stipulates that the K symbols after a group of continuous SBFD symbols are the first symbol set, such as Figure 7 The K symbols corresponding to T_switch_1 are the first symbol set. The terminal determines the first symbol set according to the K value and the positions of the K symbols specified by the protocol.

[0237] Alternatively, the base station indicates the third information through RRC signaling, and the third information is used to determine the parameter α, and the parameter α is used to determine the number of symbols K of the first symbol set. The protocol stipulates that the K symbols before a group of consecutive SBFD symbols are the first symbol set. The terminal determines the first symbol set according to the parameter α and the protocol. For example, the number of symbols K of the first symbol set is Where T is the symbol length. For another example, the number of symbols K in the first symbol set is Where T is the symbol length, N TA,offsetDetermined by n-TimingAdvanceOffset or according to the table in the protocol.

[0238] Alternatively, the base station indicates the position of each symbol included in the first symbol set through RRC signaling. For example, the base station may further configure the first symbol set in the symbol configured as D, U or F through tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. For example:

[0239] tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated configure slotn+2 to D, and the base station uses RRC signaling to Figure 7 The symbols in slotn+2 are further indicated as {TTXXXXXXXXXXXX}, where {TT} represents the first symbol set and X represents the SBFD symbol. The terminal determines the first symbol set according to the RRC signaling instruction of the base station.

[0240] If the sending / receiving opportunity partially or completely overlaps with the first symbol set, the terminal discards the sending / receiving opportunity, delays the sending / receiving opportunity, or the terminal performs rate matching on the part where the sending / receiving opportunity does not overlap with the first symbol set.

[0241] It can be seen from the above description that the solution of the embodiment of the present application can solve the problem of switching between SBFD and traditional symbols, thereby reducing the complexity of base station scheduling.
